This is my covenant with you and your descendants after you, the covenant you are to keep: Every male among you shall be circumcised.111
You are to undergo circumcision,2 and it will be the sign of the covenant3 between me and you.
For the generations to come4 every male among you who is eight days old must be circumcised,5 including those born in your household or bought with money from a foreigner--those who are not your offspring.
Whether born in your household or bought with your money, they must be circumcised.6 My covenant in your flesh is to be an everlasting covenant.714
Any uncircumcised male, who has not been circumcised8 in the flesh, will be cut off from his people;9 he has broken my covenant.10"
God also said to Abraham, "As for Sarai11 your wife, you are no longer to call her Sarai; her name will be Sarah.1216
I will bless her and will surely give you a son by her.13 I will bless her so that she will be the mother of nations;14 kings of peoples will come from her."
Abraham fell facedown;15 he laughed16 and said to himself, "Will a son be born to a man a hundred years old?17 Will Sarah bear a child at the age of ninety?"1818
And Abraham said to God, "If only Ishmael19 might live under your blessing!"2019
Then God said, "Yes, but your wife Sarah will bear you a son,21 and you will call him Isaac.a22 I will establish my covenant with him23 as an everlasting covenant24 for his descendants after him.
And as for Ishmael, I have heard you: I will surely bless him; I will make him fruitful and will greatly increase his numbers.25 He will be the father of twelve rulers,26 and I will make him into a great nation.27
